John Whitehead was an English explorer, naturalist and professional collector of natural history specimens in Southeast Asia. He is the first documented person to reach the summit of Mount Kinabalu: this was in 1888, after annual attempts from 1885.

The Corsican nuthatch is a species of bird in the nuthatch family Sittidae. It is a relatively small nuthatch, measuring about 12 cm (4.7 in) in overall length. The upperparts are bluish gray, the underparts grayish white. The male is distinguished from the female by its entirely black crown. The species is sedentary, territorial and not very shy. It often feeds high in Corsican pines, consuming mainly pine nuts, but also catching some flying insects. The breeding season takes place between April and May; the nest is placed in the trunk of an old pine, and the clutch has five to six eggs. The young fledge 22 to 24 days after hatching.
